Peter Andre felt "sick" when he turned 40

He said: "I'll give you my honest opinion about the 40 mark. When I got to 40 I hated it but don't worry it gets good. So 40 I remember the day - I had only just recently lost my brother before that so I was in a bad spot. I woke up on the day of 40 and I was trying to be happy because everyone had done so much for me but I saw the four and zero written down and it made me feel sick. My sister said she hated turning 40, so I asked her 'how long did it last for?' and she replied a year."

However, the 47-year-old singer thankfully "chilled out" as soon as he reached 41.

Speaking on Jess Wright's Girls No Filter podcast, he added: "But when I turned 41, I don't know what happened but I completely chilled out, I became a completely different person. I'm happy about life, I'm always chilled and I really do think forties are insane ... The thirties for me was also weird, it was a mid-life crisis because I knew I wasn't a kid and I knew I wasn't a man. Whether it's in your late thirties or forties you're going to feel like your life has started again."

Meanwhile, Peter previously revealed he is planning on working until he's 55.

He said: "I've got my US visa approved and I'm desperate to go. I jokingly said I was going to retire at 50, but I’ve found this new hunger for songwriting and acting. I’ve added another five years on."

And Peter previously insisted he wants another baby but is giving his wife just one more year to have a baby as he doesn't want to be changing nappies when he reaches the age of 50.

He said: "A baby would be amazing. We keep saying yes, we keep saying no. I think maybe! ... It's tough, because if someone says to the guy, 'Do you want another child?' you're just thinking, 'Oh yeah, let's try, why not?' We have discussions all the time.

"I said to Emily, 'If you want another one then we have to start trying now.' I'm 47 and I don't want to be changing nappies at 50 because I've done it so many times over the last 15 years. This is my last year that I would be willing to try, because then I’m over the nanny stage for good. Unless you're someone like Simon Cowell, having his first baby in his 50s."
